sc'rIoNAI. WHEEL-RIM.

1'0 all whom t may concern Be it known that I, Rosoor: R. ROYAL, acitizen of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented new and usefulImprovements in Sectional f'heel-Rims, of which the following is aspecification.

The object of the present invention is to provide a rim for a wheeland-means for securing a tire thereto, of cheap and simple constructionand such .that the tire can be quickly removed and replaced.

In the accompanying drawing, Figure 1 is aside view of a rim of-a wheelconstructed in accordance with my invention; Fig: 2 is an. enlarged'partial cross-sectional View thereof.

Referring to the drawing, 1, 2 indicate felly sections, each completelyannular in forni, of which the section lhas a central narrow inwardlextension 3 'formed vwith sockets 4 to receive the spokes of the wheel.The section 1 is much thicker on .oneside than on the other, yand thesection 2 surrounds the inner portion 6 of the section 1, and thecombined thicknesses of the section '2 and the thinner portion 6 of `thevsection 1 are equal to` the. thickness of the-thicker portion of thesection 1. Said thicker portionof the section i is spaced from thesection 2 a sufficient distance to receive therebetween two annularflanges 7 extending inwardly respectively from the inner or adjoiningedges of rim sections 8', the outer edges 9 of which are hook-shaped toengage and hold correspondingly shaped edges of a. tire of the usualform.- Said felly section 1 is formed with a 'groove 11, in which areSpecication of Letters Patent.

placed at suitable intervals, three being here shown, locking blocks 12.Bolts-13 are passed through holes in said blocks, in the thlcker portionof the section 1, inthe inwardly lextending flanges 7, and in the sec't1on @and nuts 1-1 are secured on the ends of. sald bolts. These bolts,by compressing y very firmly the two annular fianges between thesections 1 and 2,'iir1nly hold the rim sections together and therebyhold the tire in place. 'At the Sametime itis readily seen with howgreat ease and rapidity the tire-'can be removed, all that is.necessaryv for that purpose being to unscrew the three or more nuts 14,when the two rim sections can be separated and the tire thus removed.

In combination, felly sections, one of which is thicker on one side thanon the other, the other section surrounding the thinner portion of thefirst-named section, rim sections having annulaiflanges extendinginwardly from their inner or adjoining edges, said sections being spacedfrom each other a suiclent'distance to recelve therebetween saidflanges, registering holes in the thicker portion of the first-namedsections, in the inwardly extending flangesl and in the other section,bolts through said holes and nuts on the ends of the' bolts, and fbolting together the 'felly sections and the rim sections.

In testimony whereof I have hereunto set mv hand in thepresence oli-.twosubscribing Roscoe R. ROYAL. Witnesses F. M. WRIGHT, D. B. RICHARDS.
